upon a set of cores to provide a series of toilet i-rolls are automatically stripped therefrom WVhile the end of the empty core shaft is still rolls equal in their combined length to the Width of the original Web.- Upon thecompletion of the re-winding operation whereby these rolls are formed, the operator removes fromthe re-winding machine a complete set of rolls and substitutes in the re-winding machine a core shaft bearing merely empty cores. I v I It is the function of the present apparatus to receive the full core shaft and supply a core shaft having the necessary number of empty cores. Between the point-atwhich the full rolls are received and the point where the empty cores are delivered, each core shaft follows a circuitous path across labeling apparatus which automatically applies labels to each; roll. "Thereupon the core shaft is freed automatically at one end and the full, labeled freeagirljslips empty cores onto the free end of the shaft until the shaft is filled with cores-in readiness for a subsequent re-Windring operation. Thereafter the free end 1 of the core shaft is again engageduby the conveyor which restores the core shaft to the starting point from which the operator takes it for a subsequent operation of the re-windmg machine as above explained. I

In the light of the forego ng brief descr1ption'of the operation of amachine embody ng this invention I may say that one of the prin cipal objects of'the invention is to provide an automatic labeling machine in which a core shaft maybe supported with one end free and the vvoundand labeled rolls automat- .ically stripped therefrom and new cores placed thereon, I p

It is further very important object of the invention to provide an apparatus in which the newly coredshaft is returned substan- -;tially to the startingpoint whereby an oper- MEANY,'QF.GREE1I'UBAY, Wisconsin, a oonronerron: or

It is a further very important object of the invention to provide a labeling machine in which the cells for individual staclzs oflabels are so organized as to minimize the clearance between labels of successive stacks thereby substantially completely covering each roll with its respective label. 7

Uther'objects of the invention relate to a Y no el andimproved labeling device inwhich each roll is mechanically rotated for the ap.

plication of the label thereto,therebywithdrawing the respective labels, from their guides and ensuring the application of a label toeach roll; theprovisionjof automaticelectrical controls for the apparatus; the provision of novel and improved means for stripping the labeled rolls from the full shaft; the provision ofnovel. and improved means forsup porting the respective shafts and for freeing an end of each duringthje strip.-,

For the purposes of convenient illustration I have shown a machine for handling fewer labels than would ordinarily be handled in actual practice. It is to be understood that machines embodying this in vention may be made in any practical capacity by merely increasing the dimensions of the parts and the number of labeling cells.

General organization and eowveyor system The general organization of the machine is very simple. The frame 10, best illustrated in Figures 1, 2 and 3, supports cross shafts and 1 1. Each of these, except shaft 12, carries two sprockets 15 and 16 at that side of the machine which is closest the observer in Figure 1. Each has a single sprocket 17 at the remote side of the machine. These sprockets carry conveyor chains 18, 19 and 20 respectively.

Between sprocket shafts 12 and 13 is a shaft 22 supported by an arm 23 and carrying sprockets 2 and 25 for chains 18 and 19. Chain 20, in passing between sprocket shafts 12 and 13, passes around the back side of a mutilated sprocket wheel 27, as clearly shown in Figures 1 and 3. Sprocket 27 is mounted 011 a cross shaft 28 having spring centered bearings at its ends, such as that shown at 29 in Figure 1.

The three chains 18, 19 and 20 together constitute conveying mechanism for the several core shafts or mandrels. At corresponding points the chains carry brackets 30, 31 and 32 which vary in construction according to their function. A bracket 30 constitutes a head stock within which is yieldably mounted a spring pressed chuck 33, driven by a shaft 34, carrying a pinion 35. Bracket 31 is an open ended fork, as best shown at the left of Figure 9. Bracket 32 comprises a tail stock likewise provided with a spring pressed retractible chuck having spindle 38 headed at 39.

Each core shaft or mandrel 410 is placed in the machine by an operator standing at the left of the machine as viewed in Figures 1 and 2. In Figure 2 thehead stock 30, tail stock 32 and intermediate bracket 31 are shown open to receive a mandrel carrying full rolls requiring labels. The reduced end portion 41 of the mandrel is first inserted in the tail stock chuck 37. The fulcruniportion 12 of the mandrel is then inserted in the forked fulcrum bracket 31 of the chain 19, chuck 33 being retracted in the meantime by means of pinion 35 which is grasped manually like a hand wheel for the purpose. When the mandrel is in position, the pinion 35 is released and chuck 33, under pressure shafts mounted in their respective brackets.

Between the sprockets mounted on cross shafts 11 and 12 the labeling operation occurs as will hereinafter be more fully described. lm'mediately after the labeling of the rolls on any given mandrel, the head 39 of its tail stock chuck is engaged by a cam track 45 whereby the chuck is retracted, as shown in Figure 3 and the end of the mandrel 40 is left unsupported.

immediately thereafter sprocket 27 causes chain 20 to take a different course from that taken by chains 18 and 19 and the withdrawal of tail stock bracket 32 on the new course of chain 20 completely exposes the end of the core shaft or mandrel which is now supported entirely by chains 18 and 19, the latter being provided with a guide 46 for increased rigidity of support.

At this point in the operation of the machine the automatic roll removing mechanism hereinafter to be described commences to operate to push all of the labeled rolls from the mandrel. The movement of the mandrel continues during this stripping operation and after it moves downwardly about sprockets 241 and 25 a second operator may reload the mandrel with cores 47 (see Figures 2 and 9).

As the tail stock brackets 32 pass about the mutilated sprocket 27 they are received in the relieved portions thereof. The spring nounting of the bearing of shaft 28 takes up the slack occasioned by the straightening of the chain 20 as its brackets v32 enter the cut away portions of the sprocket.

As the chain 20 again approaches a position of alignment with chains 18 and 19 a second camguide 48, similar to cam guide 45, picks up the headed end 39 of the tail stock chuck and retracts it in order that the end portion 41 of the mandrel 40 may become aligned with the chuck to be re-engaged thereby as the head 39 passes from the cam to the position shown at the bottom of Figure 3. 7

From this point a re-cored mandrel proceeds to a position where it may be removed from the machine and inserted by the operator in the re-winder as above described.

These plates do not extend tothe tops o f the several stacksbut terminate in spaced re lation to the top of each stack, as shown in Figure l, I I 1 The platforms 55 are carried by spr1ngs'57 from cross head guides 58 having tubular supports 59. Each tubular support is provided witha bearing sleeve 60 for an elevating screw 61 journaleu in a socket 62 in the bottom ofthe respective cell. The top of each bearing socket 62 supports a worm wheel 63 connected with screw 61 and driven by a worrn 6L The pins65, carried by handles 66, pivoted to the tubular support 59, are pressed by spring 67 through openings in the tubular support 59 and the sleeve 60 into op: erative engagement with the threads or" screw 61 to constitute the equivalent of a nut for vreleasably receiving motion from the elevating screw 61. l Vhen it is desired torefill any given label cell, the handles 66 are manipulated against the compression of the spring 67 to release the pins from screw 61 and thereby, to free the cross head 58 and [false botto1n55 for downward movement so that a new stack of labels maybe placed on the false bottom between the guide parti-- 't-ions'56.

This par arranged to interact with the teeth of ratchet 77 except when the electro-magnet is enerized and on such occasions it is lifted out 11 of a position for operative engagement with ratchet.

the guides 56 n t only terminate below the top of: each label stack asrabove noted, but are relieved at their ends, as shown in Figure In order to gu de thelabels of each stack at the top of the stack I haveprovided at one end of the stack arms 82 which, are pivoted and subject to the tension of springs 83 which tend to hold guide-portions 8st of these; arms at the level of the top of the stack, subject, however, to yielding movement when the arms aretravcreed by. toilet rolls.

It will be understood that the rolls 53 contact at their ends, being. re-woundiirom single longitudinally slitt-ed web.

This finger is' fulcrumed at 101 tive racks and mounted on rock shafts 119 labels have been used to relieve the pressure on the guide or spring finger and thereby to permit the contacts to open. 7

Before describing the manner in which the labels'are applied to theroll, I shall now dely, which are mounted on racks 109 and 110, provided with rack teeth 111, and arranged for reciprocation in vertical guides 112. The

pasting bars normally hang by gravity at substantially the angle indicated in Figure 1 at the left but each of the rock shafts 107 and 108 is provided with a finger 113 which, in the lowermost position of the respective rock shafts, interacts with a stationary stop 114 to oscillate rock shaft 108 to a position in which the bar 106 will be vertical and its lower margin will be directed flat upon one end or the other of the uppermost label of each stack. Additional stops 115 are positioned above the path of travel of arms 113, as shown in Figure 2 and Figure 10, so that during the upward movement of the respective racks 109 and 110 arms 113 will be en gaged by stops 115 to oscillate the respective rock shafts 107 and 108 counter-clockwise, as viewed in Figure 10, to bring the paste carrying lower edges of the paster bars 105 and 106 into contact with the paste carried by rolls 116 which operate in paste receptacles 117 and are chain driven from shaft 22.

In order to provide for the vertical reciprocation of the racks 109 and 110, I employ segments 118, meshing with the respecsupported from the upright guides 112. An arm 120, connected to each rock shaft, hangs in the path of movement of mandrels 10 so that the passage of each mandrel will lift the paster out of the path of the rolls carried by the mandrel, bringing its pasting margins into cont-act with the paste peripherally carried by roll 116, and allow the gravity return of the paster into engagement with the next successive label after the roll has passed.

It will be noted from Figures 7 and 8 that the paste bearing margins of the paster bars 106 are notched at 122 to clear the fingers 100 of alternate label cells. In the type of cell shown in Figure 5 the paste bearing margin of paste bar 106 engages the label between the top plate of guide 90 and the end of the label and no notch is required.

Engagcmcntof the roll with the label As the conveyor chains carry the respect-ive mandrels 40 along the top of the machine, the pinions 35, connected with driving chucks 33 in the head stock brackets 30, will mesh with the stationary rack 125 (see Figures 1, 3 and 4). It is expressly to be noted that the pinions 35 are smaller in diameter than the rolls 53 which require labels. Because of this fact, the rolls 53- are rotated somewhat more rapidly than would be the case if they were merely contacting at their peripheries with a stationary surface.

As each roll clears the clip 86' and rolls onto the adherent end of its respective label, from which the paster bar has been removed by the advance of the mandrel, the label will stick to the outer periphery of the roll and hence will free itself from the clip 86. If the mere rolling contact of the respective rolls with the respective labels were relied upon to wind the labels upon the rolls, the result would by no means be certain since the rolls might not have uniform pressure engagement with their respective labels. In the arrangement disclosed, however, the relatively rapid rotation of the rolls not only positively winds each label upon its roll but also withdraws the remote end of each label from beneath its contact guide comprising, in the Figure 5 construction, the guide 90,.and in the type of cell shown in Figure 7, the contact finger 100. Thus, before the roll reaches the guide, the label has been completely wound upon it and has been sealed at the point of overlap by the pressure engagement of the roll with the stack of labels therebeneath.

Ziemoval of labeled rolls from the mandrel As the tail stock frees the end of mandrel -10 the labeled rolls carried by that mandrel become subJect to the automat1c operation of evice which slides the whole series of rolls in the mandrel.

Threaded upon a feed screw 130 is a forked arm 131. The feed screw driven forwardly and reversely by means of motor 132 and gearing at 133.

a mandrel 10 approaches the position for discharge of its labeled rolls, it enters the forked end of arm 131 which has been left approximately in the position shown in Figure 1 by friction between the screw and the arm during the clockwise rotation of the screw, (as viewed in Figure 1) which has restored the arm to its initial position.

As the mandrel continues to move, the fork 131 commences to oscillate upon the screw 130 in a clockwise direction, as viewed in Figure 1, and the linger 135 carried thereby engages switch 136 there-by initiating the operation of motor 132 in a counter-clockwise direction. lhis causes the forked arm 131 to feed along the mandrel during the continued movement of the mandrel and thereby to force all of the labeled rolls from the free end of the mandrel. At the conclusion of this operation, the forked arm will have swung an traveled to a position where it will enduring the continued operation of the'scre'w," to zts original starting point at the s de of theniachine. Here the finger 135 will strike the stoo switch 139 thereby bringing paratus to rest." I

The

at'the right in Figured Drz -m'ag connections and summary of operaftiong I The ma'in'drive fo'r'the' machineis derived from a motor 150 and I'QClLlCtlOIlgearing at 151 and 152to' shaft 153 which carries a.

pinion 154; meshing with a gea'r 155on the cross shaft 14 which carries sprockets'15 16' and 17 for the respectiveconveyorchains. I

and thereby cause each pasting bar successively to move upwardly out of the path of the rolls, acquiring'a fresh charge of adhesive, and subsequently return to the next successive label. 1

Immediately after the mandrel passes clear of the label cells, one end is freed due to the engagement of the head '39 of the tail stock chuck 37 in retracting cam 45. This Withdraws the chuck 37. from the mandrel and immediately the chain 20, bearing the tail stockbracket 32, assumes acourse entirel r passage of chain 20 around the, back sidefof sprocket 27"leaves the end of mandrel 40 entirelyclear, as best shown inthe diagram matic view comprising Figure 9. i, l As the mandrel movement continues,"the

While the end of the mandrel is still clear in passing about the back of the machine,

the mandrel is re-cored by simply slipping cores 4'? onto the exposed end thereof. Im-j mediately thereafter thehead 39 of tail stock chuck 37- is again picked u by a retracting cam 48 and'chai'nQO is restoredto alignment with chains 18 and 19, and tail stock chuck 37 is brought into registry with mandrel 450 1 while the chuck is thus-retracted.
